Novel low-temperature pyrolysis treatment device for household waste

Abstract

The invention discloses a novel low-temperature pyrolysis treatment device for household waste. The device comprises a furnace body; one side of the furnace body communicates with a feeding device; the upper end of the furnace body is provided with a secondary combustion chamber; the furnace body communicates with the secondary combustion chamber through a smoke collecting device; the upper end ofthe secondary combustion chamber is provided with a heat conduction chamber and a smoke collecting chamber in sequence from bottom to top through a partition plate; the smoke collecting chamber is provided with a smoke exhaust pipe; a heat transfer water tank is arranged in the heat conduction chamber; the two sides of the heat transfer water tank are each provided with a water delivery pipelineextending out of the heat conduction chamber; and a plurality of first pipelines are arranged in the secondary combustion chamber. The device is reasonable in integral structure design, and is horizontally arranged relative to all structures, so that space is saved; meanwhile, the furnace body is arranged underground, so that the waste is relatively convenient to dump; meanwhile, the device givesconsideration to the environmental protection function, and smoke is directly led out for secondary combustion from the interior of the furnace body; meanwhile, the heat of secondary combustion is utilized to supply hot water and central heating; the practicability is high; and reutilization of waste resources is realized, so that the sustainable development of the environment is facilitated.

Description

technical field [0001] The invention relates to a pyrolysis treatment device, in particular to a new low-temperature pyrolysis treatment device for domestic garbage. Background technique [0002] The pyrolysis method uses the thermal instability of organic matter in garbage to heat under anaerobic and anoxic conditions to cause thermal cracking of organic matter. Since large molecular organic matter is converted into small molecule combustible gases (such as hydrogen, carbon monoxide, methane and other hydrocarbons, etc.), liquid fuels and solid fuels. In the prior art, there are two problems in the existing combustion equipment. One is that the use of low-temperature pyrolysis to burn the combustible gas after pyrolysis of garbage is not sufficient, and the content of toxic substances in the discharged gas is high, which is not conducive to the urban environment. Second, the structural design of most existing equipment is unreasonable and takes up extra space; third, the r...
